Developer is invisible? stay away. *2023-04-07* I switched my review to 1 star because the developer is nowhere to be found, and unresponsive for years. It’s ridiculous thee isn’t an AUv3 version of this to use with iOS daws. Tried to contact the developer, he’s a ghost. Going to put in for a refund. Another dud iOS app. Truly dumb and disappointing. Grrrrr. Stay away folks. ### 4/5 — Please make these compatible with AUM! *2022-11-30* Please make these compatible with AUM! ### 1/5 — Does not randomize notes *2022-10-22* The note offset either picks a single repeated note or is even ignored. The velocity works as expected but that is worthless to me without the notes. ### 2/5 — gut aber *2021-09-30* gute app, wenn sie auch als AU in AUM funktionieren würde. stürtzt aber in AUM leider ständig ab, schade. ### 4/5 — Working well *2019-03-25* Would be great to have this as an regular midi effect in other hosts too though. ### 4/5 — Great ideas, needs expanding *2018-03-20* Having bought into the whole MidiFlow package, it’s a great idea when it works. It may be more an AudioBus fault than this app, but when things fall over it’s annoyingly. The one thing this, and it’s sisters need, is compatibility with apps other than AudioBus. Starting with AUM. Nic ## Frequently asked questions about Midiflow Randomizer (Audiobus) ### What is Midiflow Randomizer used for?
